Tunnel Vomp, Austria
		The Project: Construction of a railway tunnel with a length of 8000 m. Executing companies: ARGE Tunnel Vomp, Österreich Strabag AG Ed. Zübiln AG Hochtief Construction AG   The Problem: Drainage during the earth tunnel heading with the aid of submersible pumps.
Our Solution: Use of Tsurumi type KTV2-22, KTV2-55 and KTZ32.2 in 24-hour snore mode.A total of some 35 Tsurumi pumps are in use.		KTZ32.2 in use for drainage at the working face.
		Figure on left: To be seen here is a KTV2-22 which has been taken apart for cleaning. Just four screws have to be released to expose the pump hydraulics. The lateral guiding of the medium makes removal of residues of concrete a simple matter. High savings in costs can be achieved through the simple form of construction of the Tsurumi pumps.
In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
